There is no device shown for con- 55 veying the cap from thestamp 3 to the tool 4, 21 and from there to the capping tool as saiddevice does not lie within the scope of this invention and'may becarried out in different ways. The most simple and suitable one is apneumatic device employed in this kind of capping machines in recentyears.

The invention relates more particularly to the mechanism by which theinsertion member obtains its motion. The purpose of the invention is toarrange in this mechanism or motion device a resilient connecton of suchnature that it gives to the insertion member a certain spring in itsdirection of motion so that, independent of the rest of the motiondevice, it may stop if it meets an abnormal resistance during theinsertion motion.

Below the table 22 is a two-armed lever or balance 26 mounted in a fork2'7. One end of the balance is by means of a pivot 28 connected to theinsertion member and by means of another pivot 29 connected to avertical push rod 30. Above said rod there-is another push rod 31 inalignment with the former. This rod 31 lies in a bore 32 in the member32 fixed on the slide 7 and has its upper end forked to receive a roller34 which, by a spring 36, acting on the forked end, is held pressedagainst a cam disk 38 of the machine shaft 2. When the rod 31 by the camdisk is pushed down its motion is transferred to the rod 30 by a spring40. Said spring is enclosed in a sleeve 41 which is constricted at thetop and' which is mounted on the rod 31 by means of a pin 42. Into thelower end of the sleeve 41 is screwed a sleeve 43 which is adapted toslide on the rod 30. The spring 40 rests with one end against the top ofthe sleeve 41 and with the other end against a ring 44 which is mountedon the rod 30. When the rod 31 is raised by the spring 36 it, in itsturn, raises the rod 30 by means of the sleeves 41 and 43 and the ring44. By means of the screw sleeve 43 the spring 40 is more or lesscompressed in order to regulate the pressure of the insertion member 21against the cork disk. The tension of the spring is adjusted so that ifthe part 21 meets a greater resistance than is normally necessary forthe insertion of the cork disk into the cap the spring is compressedwhereby the sleeve 43 slides on the-rod 31.

This motion of the two sleeves 41 and 43 relative to the rod 31 isutilized to declutch the drive device of the machine.

For this purpose the sleeve 41 is provided with a small arm 46 adaptedto be swung on a pivot 4'7 in the upper end of the sleeve. The lower endof this arm has a cam face 48 which at the downward motion of the sleeve41 when the rod 30 stands still meets a corresponding cam surface of aring 49 secured to the rod 30 which results in that the arm 46 is turnedto the left in the drawings (Figure 2) and pushes against a push member50- mounted in a guide 51 of the slide '7. The push member 50 engagesand moves an upright rod 53 the upper portion of which is pivoted asindicated at 53 to accommodate this movement. The rod 53 is mounted toslide vertically and is guided partly by means of the table 22 throughwhich it passes and partly by a guide member 54 fixed on the frame 1.When the rod 53 is displaced by the movement of the push member 50 theupper extremity thereof is moved in the path of a shoulder 54 carried bythe slide 5.

The slide 5 in Fig. 1 is shown in its uppermost position and during thedownward movement J thereof, if the rod 53 is disposed in the path ofthe shoulder 54, said rod 53 is moved downwardly.

The displacement of the rod 53 is utilized to automatically interruptthe operation of the machine and with this object in view the rod 53 isextended downwardly toward the lower part of the machine as illustratedin Figs. 7 and 8 and operates a friction coupling. The friction couplingis illustrated at '7576 and may be of a conventional type adapted totransmit motion from a driving belt pulley 77 to the shaft '78 fromwhich latter motion'is transmitted to the different parts of the machineby well known power transmitting devices such as gear wheels 78. Thecoupling element 75 is movable longitudinally on the shaft as usual bymeans of a collar 79, the collar being connected with rods 80 whichlatter in turn are connected with short upright arms 81 on the shaft 81pivotally mounted on the base of the machine. The shaft 81' is providedwith another arm 82 disposed in a substantial horizontal position andconnected through a rod and lever 8384 with the lower extremity of therod 53. -Thus when the rod 53 is depressed by the shoulder 54 an upwardmovement is imparted to the arm 82 through the lever 84 and rod 83 andby means of the arms 81 and rods 80 the coupling element '75 isdisplaced so as to disengage the companion coupling element '76 againstthe tension of the spring 85 and in this manner the operation of themachine is interrupted. I

,The machine operates in the following manner. single rod. Should therearise any perturbation when laying in the cork the part 21 willimmediately meet agreater resistance than the usual and normal one.Consequently, movement of the part 21 is arrested but movement of themembers 33, 31 and 41 continues. As the rod 30 is directly coupled withthe member 21 through the lever 26, its motion is also arrested, andduring thedescending movement of the sleeve 41 and arm 46, the extremityofthe latter engages and is swung outwardly by the cam ring 49 resultingin actuation of the push member 50 and the actuation of the controldevice connected therewith.

The same will be the case, as already mentioned, even if there is nocork disk or if the disk-is broken- There is namely a stopping member 64in the machine table 1 which member is movable towards and away from theinsertion member 21. If there is no cork disk or if the bore for themember 21 is not entirely filled (viewed in the cross direction) by acork disk inserted into the same the stopping member, by the action of aspring 65, engages a recess 67 of the part 21 and prevents it frommoving upward (see Figure 3). As is clear from Figure 1, the spring islocated between a shoulder 68 of the part 64 and a sleeve 69 which isscrewed into the hole for the stopping member in question. When, on theother hand, a whole cork disk is fed to the insertion position itcarries away the stopping member so that the part 21 may be pushedupward. Also this device operates quite automatically,. as will beeasily seen.

Cork particles which may'lie on the member 21 are pushed down by thecork disks into a waste chute 72 which in the drawings is shown disposedin the member 21, but which may also be disposed laterally thereof. Asto the members 46, 50 and 53 they may be substituted for by for instancethe device shown in Figure 4. Instead of Normally the two rods 30, 31move as a the swingable arm 46, the sleeve 41 is provided with astationary arm 57 having a push tap 58. This co-operates on one handwith the ring 49, on the other hand with an angle-lever 59, which isconnected to the rod 53, By this arrangement the machine may bedeclutched without the cooperation of the slide 5.

It need hardly be pointed out that the described device also isapplicable to other disk packings than to those of cork, and also inother machinal combinations.
